Problems solved by technology

[0003] The active ingredients in maca cannot be completely extracted with alcohol, such as polysaccharides, which will be incomplete, so water extraction is used. Conventional extraction of maca powder has poor fluidity, uneven extraction temperature, partial coking, and the taste of the extract is not good. 1. The extraction of nutrients is not complete, the solid and liquid of the extract cannot be effectively and quickly separated, and the solution cannot be clarified; the dried substance cannot be loose and porous, and it is difficult to dissolve after adding water

preparation example Construction

[0019] The preparation method of the high-stability maca extract of the present invention comprises the steps of pulverizing, extracting, separating, filtering, concentrating and drying, specifically comprising:

[0020] A, pulverization: take raw maca, pulverize through 60~250 mesh sieves;

[0021] B. Extraction: Put the crushed maca into the extraction tank, add water with a solid-to-liquid volume ratio of 3~8 times of maca, extract at 60~100°C for 1~8h, and extract 2~5 times in a cycle to obtain the extraction mixture ;

[0022] C. Separation: Centrifuge the extraction mixture at a centrifugal speed of 2500~3500r / min;

[0023] D. Filtration: Filtrate the centrifugate to obtain the filtrate;

[0024] E. Concentration: Concentrate the filtrate to a relative density of 1.08-1.25 to obtain an extract;

[0025] F, drying: dry the extract to a water content of 1-5% to obtain the target Maca extract.

[0026] The extraction tank described in step B is one of straight cone extr...

Abstract

The invention discloses a high-stability maca extract and a preparation method, a preparation and application thereof. The high-stability maca extract is prepared by the steps of taking maca as a raw material, grinding, extracting, separating, filtering, concentrating and drying. The maca extract is prepared by extracting by using a straight tapered type forced external circulation extraction tank, so that the flowability is relatively good, the extraction temperature is relatively uniform, and the local coking is effectively prevented in the extraction process of the maca powder, and the taste and the nutrient content of the extract are ensured; a countercurrent horizontal spiral discharging decanter centrifuge is used for separating, so that an extracting solution is effectively and quickly separated, the clarification property of a solution is relatively good, and the thorough solid and liquid separation of the extract is ensured; the dried matter is loose and porous, and the dried matter is quickly and fully dissolved after being added with water, so the extract is convenient to drink; the water activity is reduced to 0.6 or less, the microbial growth and reproduction are inhibited, and preservatives or bacteriostatic agents do not need to be added, so that the dried product does not deteriorate after long-term storage. Meanwhile, the produced dry maca extract powder is convenient to carry.

Description

technical field [0001] The invention belongs to the technical field of food deep processing, and in particular relates to a high-stability maca extract and its preparation method, preparation and application. Background technique [0002] Maca is a plateau plant of the cruciferous family, native to the plateau plant above 4,000 meters in the Peruvian Andes in South America. The protein content is 15.7%, which can effectively balance the nutritional intake of the human diet; the combination of starch and protein in maca can effectively form glycoprotein, which has the effect of lubricating joints and protecting mucous membranes; Injection can effectively improve the immune function of the human body, and has the functions of inhibiting tumors, inhibiting bacteria and detoxifying, etc.; the dextrin component in Maca can effectively improve the erection time and hardness of men; Maca is rich in 20 kinds of amino acids, of which 16 kinds of amino acids required by the human body...
